Abstract

Ce roulement mécanique (2), comprend une bague extérieure (4) et une bague intérieure (6), centrées sur un même axe de roulement (X2), la bague extérieure étant disposée radialement autour de la bague intérieure, et une cage, disposée coaxialement entre la bague intérieure et la bague extérieure et logeant des éléments roulants (10). La cage est formée par plusieurs portions tubulaires disjointes (8A, 8B, 8C, 8D) qui, à l'état assemblé du roulement, sont séparées les unes des autres d'un interstice (I1) non-nul.This mechanical bearing (2) comprises an outer ring (4) and an inner ring (6), centered on the same bearing axis (X2), the outer ring being arranged radially around the inner ring, and a cage, arranged coaxially between the inner ring and the outer ring and housing rolling elements (10). The cage is formed by several separate tubular portions (8A, 8B, 8C, 8D) which, in the assembled state of the bearing, are separated from each other by a non-zero gap (I1).
